The TX-RZ740 not only elevates sound, but also that satisfied feeling you get every time you switch it on. The extra weight of the custom transformer, custom 10,000 uF capacitors, and aluminum heat-sink speak of an amp built for high-current power, enabling 3D audio to exhibit true-to-life spatiality and pin-point localization. Bass force is terrific, dynamics blindingly fast, and resolution grainless. SMART A/V Receiver™ gathers multi-room platforms supported by 802.11ac1 Wi-Fi®, or enjoy powered and unpowered audio distribution. The receiver, which supports up to 7.2.4-ch of 3D sound with external amp, is certified for IMAX® Enhanced and is THX® Certified Select™ for a theater-reference experience. From how it sounds to the way it makes you feel, the TX-RZ740 is made to savor now and in the future.
Our RZ Series takes performance and build quality to the next level for a reference-level experience. Custom high-current transformer, block capacitors, and other upgraded parts deliver 5 Hz-100 kHz frequency response for wall-shaking bass, clean treble, and fast dynamics. RZ Series supports a variety of home theater and multi-room layouts to suit you, while details such as 12 V trigger, RS-232C, IP Control, and IR input make home integration easy.
SMART AV Receiver is the heart of your home entertainment system. Access streaming content from Amazon Music, Pandora®, Spotify®, TIDAL, Deezer, and TuneIn and share sound as part of a multi-room system via Works with Sonos, Chromecast built-in*, AirPlay 2, DTS Play-Fi®, and FlareConnect™.
* The unit may automatically download and apply an Over-the-Air software update during setup.
IMAX Enhanced* A/V receivers feature DTS:X sound technology optimized for the IMAX® signature experience, reproducing the full dynamic range of IMAX theatrical sound-mixes available with digitally re-mastered IMAX Enhanced content. A pre-set IMAX Mode reproduces audio at the highest levels and delivers IMAX Enhanced content as the filmmakers intended. IMAX Enhanced versions of a range of films, from Hollywood blockbusters to documentaries, will be released for 4K HDR streaming and Ultra HD Blu-ray™.
*Enabled with a future firmware update.
Stream any music from your smartphone, laptop, or PC to the receiver with ease. Control playback with Chromecast-enabled apps you know and love from your iPhone, iPad, Android™ phone or tablet, Mac or Windows® laptop, or Chromebook™. If you have a smart speaker featuring the Google Assistant, you can cue, play, and control music playback by voice.
Note: The unit may automatically download and apply an Over-the-Air software update during setup.
The TX-RZ740 can join your existing Sonos Home Sound
System, or be the start of a new one, just by pairing it with a Sonos Connect*. The AVR ties into the Sonos ecosystem, waking, changing inputs, and playing at the desired volume on command from the Sonos app*.
*Sonos Connect sold separately. Sonos app is available free for iPad, iPhone, and Android™ at the App Store and Google Play. Please confirm device and OS compatibility before installation.
When playing any Dolby® format, engaging Dolby Atmos
Height Virtualizer* enables a more immersive listening
experience, creating a virtual surround and height effect from
traditional speaker layouts without employing additional

Dolby Atmos® and DTS:X® formats map sounds in 3D space, allowing them to move around the room and immersing your audience in the film. With 11.2-ch pre-outs and 11-ch processing, you can enjoy 3D sound through a 7.2.4 layout (external power amp required), or use built-in amps for a 5.2.4 or 7.2.2 layout. Enjoy classic titles through your height-enabled speaker system with Dolby Surround® and DTS® Neural:X finding cues in legacy soundtracks and upmixing for spatial playback.
Enjoy support for HDR (High Dynamic Range) video including HDR10, HLG, Dolby Vision®, and BT.2020. The 4:4:4 color space is also supported. Seven HDMI inputs, ARC-ready MAIN OUT, and SUB OUT pass 4K/60p and HDR video from player to compatible TV and projector and all terminals are HDCP 2.3 compliant.
High-quality AKM 384 kHz/32-bit D/A conversion is enhanced by VLSC™ filtering (Front L/R channels), an original technology that erases digital noise arising from D/A conversion. Enjoy the purity of Hi-Res Audio sources, CD, and streaming music.
Orchestrate audio playback in up to three rooms at once using
the Onkyo Controller app. The TX-RZ740 has two extra
DACs to distribute unique or synced D/A audio sources via
Zone 2 and Zone 3 speaker outputs, including HDMI®/SPDIF/
NET/Bluetooth®. With nine amps, you can enjoy a 5.2.2-ch
layout in Main with powered Zone 2 audio, or a 5.2-ch
surround system in Main with powered audio distribution to
Zone 2 and Zone 3.
Note: HDMI and SPDIF support PCM audio only. Zone 2 HDMI audio available on inputs 1-3. Zone 3 supports analog/NET/Bluetooth.
Connect your supported hi-fi system via analog RCA input to the AVR's Zone 2/Zone B line-out. In Zone 2 mode, you can play the same or different analog/digital sources (including SPDIF and HDMI) in either or both rooms at the same time. Zone B mode is an ideal match for a supported wireless transmitter. Listen to any source through wireless headphones for disruption-free late-night TV entertainment.
DAA stabilizes power delivery for accurate speaker control and spectacular dynamics. High-Current Low-Noise Power Transformer and 10,000 uF custom high-current smoothing capacitors deliver power instantly while non-phase-shift amps reproduce a wide 5 Hz-100 kHz spectrum. An extruded aluminum heat-sink controls the pitch of resonance frequencies, limiting mechanical noise. Behind the front panel are hand-selected or custom fabricated parts with digital boards separate from analog circuitry. The result is visceral musicality that makes every note an emotionally moving experience.
Additional refinements control noise, boost power, and improve S/N performance. A new HDMI® board has shorter signal-paths and large, well-finished grounds for A/V signal integrity. SoC is isolated to reduce interference noise. The power-supply line is reinforced in pursuit of smooth power delivery. These contribute to punchier bass and improved localization on an expanded soundstage.
AccuEQ Advance room acoustic calibration uses nine-point mic measurement to calibrate and EQ speakers and subwoofers and remove standing waves that arise when sound from the speakers resonates with sound reflecting off the walls, compromising its proper expression. During the process, background noise is ignored to ensure accurate equalization. AccuReflex optimizes 3D sound through height speakers by resolving phase-shift, resulting in a cohesive sound-field.
DTS Play-Fi technology allows you to enjoy quality music from
online services, media server, and mobile device to any number
of compatible products
using Onkyo Music Control
App. DTS Play-Fi technology

The TX-RZ740 features a 12 V trigger output for an external component and an IR input for remote-control range extension. It supports IP control, RS-232C, and OSD output for custom installers. An optional rack-mount kit is also available.
Apple AirPlay 2 lets you effortlessly stream music or podcasts to multiple audio devices throughout your home using any Apple device or by asking Siri - and it all stays in perfect sync. Create multi-room groups or stream to just one device.
*Apple Airplay 2 available via future firmware update.
Built-in 5 GHz/2.4 GHz Wi-Fi provides network stability for streaming, Onkyo Controller app, and multi-room audio. Bluetooth wireless technology is also on board for easy mobile or laptop connection.
Find and stream music from iPad, iPhone, Mac, and PC over the Apple AirPlay wireless audio platform. Further, Amazon Music, Spotify, TIDAL, Deezer, Pandora®, and TuneIn are all baked into the system GUI, making selection easy using Onkyo Controller or Onkyo Music Control App.
A powerful SoC (System on a Chip) processes multiple tasks at once. It evolves network functions with support for high-speed 802.11ac (2x2 MIMO) specification while compatible with 802.11 b/g/n dual-band routers.
*Note: Some countries or regions have regulations that affect wireless signal strength and the use of Wi-Fi channels.
Vocal Enhancer solves inaudible dialog in TV programs and movies. DSP technology identifies voice frequencies so you can conveniently adjust them using remote-control keys or controls on the front panel.
